Save the Penguins with five targeted demos. n=23( 12M, 11F) n=11 pre-interviews. HTE and ATES pretest/posttest. n=10 exit interviews. Equivalent scores on pretests, and 7th grade math and reading VA SOLs. Three eighth grade classes taught by the same teacher. Six 80 minute class periods. These classes were equivalent in terms of their combined 7th grade reading and math SOL scores. I used a one way ANOVA and the means were the same with a significance of p = .60. The second class was chosen as the control because there were more students in that class who took algebra in 7th grade instead of 7th grade math. I figured they might have an advantage and didn\u2019t want that to interfere with the results. The other two classes were decided with an actual coin toss. Also included in this is entrance, exit, and informal interviews with the teacher. I videotaped each class, took observation notes, and recorded group dynamics with handheld wireless microphones.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
